2 ongoing problems to sort out on my DIY 6-speed bike...
Problem #1: I have been having problems with an annoying squeaking sound from my shoes on the SPD pedals. I managed to get it to stop for a while by squirting the pedal and cleat with GT85 but the noise came back after a couple of short rides.
The release tensions on the pedals were set to minimum so I tightened them up to about halfway between min and max. That helped a little to reduce the amount of movement of the shoes.
I also adjusted the cleat positions slightly, which changed which parts of the shoes were touching the pedals. Another improvement.
The thing that eliminated the noise though was greasing the cleat recess on each shoe. Literally not a squeak from them in 100 kms of riding since then.
Problem #2: A damn ticking noise again. One of those hard to track down sounds which is both irritating and worrying. (Is something about to fail?!)
I have recently converted the bike to Hollowtech. I fitted a used bottom bracket, but the bearings seemed in good condition so I doubted that was to blame. Was it something in the rear wheel...?
I swapped in the rear wheel from my best bike. The noise had stopped! Okay, no problem with the bottom bracket, the problem had been with the wheel then...
I thought that the problem was probably in the freehub rather than the wheel bearings since the ticking noise didn't happen when freewheeling. I took the freehub off. A quick check of the wheel bearings anyway - yes, they felt fine. I took the cassette and freehub off. Quick check of the freehub bearings - ah, they felt fine too!
It was possible that the bearings only complained under pedalling load but maybe the noise came from something else? One thing that looked a bit iffy was the stack of spacers that I had used in my DIY 6-speed cassette. I reckoned that I needed another mm or two to give the lockring a bit more to bite onto. I replaced one spacer with a thicker one.
I cleaned and greased everything as I reassembled the cassette and freehub and then put them back onto the wheel. I put the wheel back in and went out for a ride...
(Immediately...)
TICK TICK... (Damn!!)
(A couple of minutes later...) TICK TICK...
(Another couple of minutes later...) tick tick...
(And then...)
tick tick...
(And finally!) Silence!
The only thing that I can think is that something was moving against something else but I hadn't quite managed to grease that interface. As the ride progressed, the grease eventually found its way in and did its job. Anyway, the bike was beautifully quiet again for the rest of the ride; hopefully it will stay like that!
This evening, something occurred to me...
I have recently converted my Devon bike to 32 mm tyres. I brought back some used 28 mm Zaffiro Pro tyres and some unused 28 mm Rubino Pros from Devon. I had worked out that my best bike (Cannondale CAAD 5) had enough clearance for 28s, which will make riding on rough Yorkshire and Lancashire roads a lot more comfortable. The Zaffiro tyres had been fitted, tested, and found to be a big improvement. The 6-speeder only had clearance for 25 mm tyres so my stock of 25s could now be reserved for that bike...
Hang on - today I had swapped in a 28-clad wheel into a 6-speed bike which I thought could only take 25s. It turns out that yes, 25s only at the front, and they are a tight fit. The back of the bike however can (just) take 28s, so I have a new plan - the Rubinos are better than the Zaffiros so they have now been put on the best bike. A 28 mm Zaffiro has been put on the back of the 6-speed bike and the other Zaffiro is a spare for that wheel. The 25 mm Continental tyre off the back is now another spare for the front. Those 2 bikes now have the biggest tyres that will fit and I have plenty of spares.
While I was working on the bikes I tightened a few stem bolts which had felt a tad loose. I also checked that the left Hollowtech crank bolts were still tight enough.
I'd really like not to have any more bike issues for the rest of the summer please, bike Gods!
